Implementation of a Two-Way Feedback (Student-Faculty) During Learning Anatomy

Background: Assessment of learning could promote deep learning, but it does not provide sufficient feedback to drive further learning and training. Although the students are subjected to some formative exams throughout the PBL units, feedback is not given appropriately and timely. We noticed that students want to know and use the reasoning behind judgments and they are always complaining that assessment criteria need to be explained. Aim of the work: The aim of this project is to implement a two-way feedback session (TWFS), in which both faculty and students have an opportunity to discuss their reflections on learning and examination processes. Methods: An Anatomy formative assessment is introduced to 100 students followed by implementation of TWFS. The faculty members provided the students with a structured and timely feedback on their performance in general and on the formative exam in particular. Also, the students reflected on the whole learning process, including the real examination experience and contents. The researcher used HSE Change model through the project and the reaction was measured using quantitative and qualitative instruments, covering level one of the Kirkpatrick model. Results: High satisfaction toward TWFS implementation was obtained. The students and the faculty recommended the implementation of this session in different courses and units. Conclusion: TWFS has been implemented and both students and faculty agreed that it enhanced the students’ learning and performance by helping them identify gaps between standard and actual performance. It also helped faculty to adapt teaching to learners needs and to keep up with their progress

Assessments of Bone Height Loss in Telescopic Mandibular Implant-Retained Overdentures Retained by Two and Four End - Osseous Implants: A Randomized Clinical Trial

AIM: This randomized clinical study aimed to assess bone height loss when using mandibular implant overdentures retained by two and four endosseous implants using the telescopic attachments. METHODS: Twelve completely edentulous patients were randomly allocated so that six patients were treated by telescopic implant overdenture retained by two implants (group A) and six patients were treated with overdentures retained by four implants (group B). Digital radiographic evaluation of bone height using Digora was made starting at the functional loading day followed by time intervals of 12 months. RESULTS: No implant loss during the healing period or after functional loading. Radiographic evaluation revealed a statistically significant difference was found between (Group A) and (Group B) were (p < 0.001). CONCLUSION: For bone loss, widely distributed four intraforaminal implants revealed more bone preservation than only two implants when using the telescopic attachments to support and retain an over dentures taking in consideration the type of the attachment will be used

Entrapment of the Martin-Gruber branch of median nerve in the forearm

We report a rare case of a dual neuro-vascular variation, which was observed in the right extremity of male cadaver. About an inch inferior to the elbow joint, three branches arose from the median nerve. These were the anterior interosseous branch, a Martin-Gruber branch (MGB) and a muscular branch. The MGB coursed infero-medially to join with the ulnar nerve by running posterior to the ulnar artery. It was surprising to observe that the MGB passed between the ulnar artery and its venae comitantes. There was an acute angulation of the MGB here, suggesting entrapment at this site

Efficacy and Safety of Intravenous Ketorolac versus Nalbuphine in Relieving Postoperative Pain after Tonsillectomy in Children

BACKGROUND: Pain is a major postoperative complication worldwide, which in turn impairs normal body performance and increases postoperative morbidity, hospitalisation, and the susceptibility to infections which also lead to chronic pain development. AIM: The purpose of this study was to evaluate the efficacy of intravenous ketorolac versus nalbuphine as analgesia after adenotonsillectomy surgery to determine the optimal procedure for pain control and postoperative reduction of analgesic use. METHODS: A group of 100 pediatric patients undergoing tonsillectomy or adenotonsillectomy were assigned as follows to two equal groups: Group A: 50 patients received intravenous ketorolac 0.9 mg/Kg. Group B: 50 patients received intravenous nalbuphine 0.25 mg/Kg. RESULTS: FLACC (Face, Legs, Activity, Cry, Consolability) pain score was measured after recovery from anaesthesia (postoperative). There was a statistically significant difference concerning pain score between group ‘A’ and group ‘B’ as pain score in 'A' (ranging from 3.18 ± 0.87 to 4.68 ± 0.74) is lower compared to 'B' (ranging from 3.90 ± 0.76 to 5.54 ± 0.73) and probability value < 0.05 except at 90 & 120 min which was observed statistically insignificant. There was no serious postoperative complication detected in either group. CONCLUSION: It is concluded that intravenous ketorolac is more effective than intravenous nalbuphine in reducing pain intensity and postoperative analgesic requirements after adenotonsillectomy in children

Multicentric vs. Unresectable Unicentric Castleman Disease with Active Presentation: An Orphan Rare Disease in a Young Egyptian Female Patient. A Case Report

Background: Castleman disease (CD) is a rare disorder that affects lymph nodes and has a wide range of associated symptoms. The affected lymph nodes show characteristic histological picture. Most of the unicentric Castleman disease (UCD) cases can be cured by complete surgical removal or radiotherapy, while multicentric CD (MCD) is much more complicated and have several subtypes and requires more effort to reach a precise diagnosis and management. Case presentation: A 17-years old female presented with sever fatigue and abdominal pain. Massive mediastinal lymphadenopathy was detected on radiological studies. Pathology confirmed a plasma cell variant of MCD. Autoimmune disorders, overlapping IgG4-related disease, TAFRO (Thrombocytopenia, anasarca, fever, reticulin fibrosis, and organomegaly) syndrome and other malignancies were excluded after a series of investigations. She was HIV-negative, and the human herpes virus-8 status was unknown. The final diagnosis of idiopathic MCD-not otherwise specified (iMCD-NOS) was reached. She showed a very good response to corticosteroids and monoclonal antibody course of treatment. Radiological investigations showed marked regression of the lymph node mass, and there was complete resolution of her symptoms and normalization of the hematological and biochemical parameters. Conclusion: The diagnosis and management of MCD remain very challenging, and the exclusion of infectious, autoimmune, and neoplastic disorders is necessary

Engagement Patterns of High and Low Academic Performers on Facebook Anatomy Pages

Only a few studies have investigated how students use and respond to social networks in the educational context as opposed to social use. In this study, the engagement of medical students on anatomy Facebook pages was evaluated in view of their academic performance. High performers contributed to most of the engagements. They also had a particular preference for higher levels of engagement. Although the students were deeply involved in the educational element of the pages, they continued to appreciate the inherent social element. The profound engagement of the high performers indicated a consistency between Facebook use in the educational context and better student performance. At the same time, the deeper engagement of high performers refutes the opinion that Facebook use is a distractor. Instead, it supports the notion that Facebook could be a suitable platform to engage students in an educational context

<i>Helicobacter pylori</i>-induced DNA Methylation as an Epigenetic Modulator of Gastric Cancer: Recent Outcomes and Future Direction

Gastric cancer is ranked fifth in cancer list and has the third highest mortality rate. Helicobacter pylori is a class I carcinogen and a predominant etiological factor of gastric cancer. H. pylori infection may induce carcinogenesis via epigenetic alterations in the promoter region of various genes. H. pylori is known to induce hypermethylation-silencing of several tumor suppressor genes in H. pylori-infected cancerous and H. pylori-infected non-cancerous gastric mucosae. This article presents a review of the published literature mainly from the last year 15 years. The topic focuses on H. pylori-induced DNA methylation linked to gastric cancer development. The authors have used MeSH terms &#8220;Helicobacter pylori&#8222; with &#8220;epigenetic,&#8222; &#8220;DNA methylation,&#8222; in combination with &#8220;gastric inflammation&#8222;, gastritis&#8222; and &#8220;gastric cancer&#8222; to search SCOPUS, PubMed, Ovid, and Web of Science databases. The success of epigenetic drugs such as de-methylating agents in the treatment of certain cancers has led towards new prospects that similar approaches could also be applied against gastric cancer. However, it is very important to understand the role of all the genes that have already been linked to H. pylori-induced DNA methylation in order to in order to evaluate the potential benefits of epigenetic drugs

Autophagy related markers (Beclin-1 and ATG4B) are strongly expressed in Wilms' tumor and correlate with favorable histology

Background. Wilms’ tumor treatment has achieved great success in the last decade. Nevertheless, some cases still fail to respond to the current multimodality therapy. These cases fall mainly in the unfavorable histology group with very few belonging to the favorable histology group. In recent years, autophagy manipulation whether inhibition or stimulation has been shown to affect cancer cell behavior and has emerged as a novel mechanism to improve cancer cell response to currently used therapeutic regimens. Objective. The current study aimed to investigate the expression of autophagy related markers (ATG4B and Beclin1) in WT, its association with the different clinicpathological parameters and its impact on patient survival. Methods. Twenty-one formalin fixed paraffin embedded (FFPE) WT specimens were immunohistochemically stained using autophagy related markers; Beclin-1 and ATG4B. All clinical, radiological and follow up data were retrieved from the patient records. Results. All specimens showed positive expression of both Beclin-1 and ATG4B. The staining score for Beclin1 varied between 50 and 300, and its expression was significantly associated with favorable histology (p=0.007). Similarly, ATG4B expression was significantly higher in favorable histology tumors compared to unfavorable histology (p=0.046). A statistically significant positive correlation between Beclin-1 and ATG4B expression was observed. The cumulative disease-free survival in patients with favorable histology was significantly higher compared to patients with unfavorable histology (p=0.0027). Conclusions. Beclin-1 and ATG4B expression were both found to be statistically significant discriminators of survival. Collectively these findings suggest that the expression of autophagy-related markers is associated with a favorable histology and could predict better survival in these patients
